I was checking out Lavera Organic Skin Care and got distracted by the following information they’ve posted regarding mineral makeup on their website.
Recent UK studies advise of strong health risks when using Titanium Dioxide (TiO2) in nano particle form in powdered mineral makeup. These inhaled TiO2 nano particles coming in contact with living tissue have a similar effect as asbestos and can cause lung cancer.
However, TiO2 is safe when contained in cream form as it cannot then become airborne. This is typically the case in sun screens. In cream form, TiO2 stays on the upper layers of the skin and does not come in contact with living tissue.
I was rather surprised because I have always regarded mineral makeup to be safer as it uses crushed minerals and unlike most cosmetics, contains no talc, chemical additives, fragrance, fillers, preservatives, or dyes. In addition, maybe I didn’t understand the second paragraph too well, but shouldn’t they be comparing with nano-based TiO2 in cream form because that’s been generally regarded as potentially risky?
I’ve written before about avoiding nano-based beauty products because nanotechnology involves manipulating properties of tiny particles, measuring one-billionth of a meter. The concern is that these particles used in skincare products can penetrate our skin, travel into our bloodstream and wreak havoc to our system. However, despite my initial concern, I am actually using a nano-based sunblock now because there is still very little factual evidence available about the harmful penetration of these nano-particles into our skin.
But my current concern is, do all powdered mineral makeup contain TiO2 nano particles and are they all unsafe? And the answer, it seems, is dependent on the actual formulation.
